Log files created, activity seen during the day, upon rolling, named file exists but is 0 bytes

Question

Seeing an issue using Log4j2 where the log file during application activity is named as: <service-name>.log ... and this file reflects current messages being logged throughout the day.

Example: Process100Server.log is reflecting CURRENT activity. At 23:59 each night, that active log file content is supposed to be reflected in that day's file which will be rolled and named, (say on the day, 09-24-2023):

Process100Server.log-2023-09-24.log

The "active" logging for the next day then goes back to a fresh log, starting all over again.

Process100Server.log

When the named file is created, somehow the expected content from Process100Server.log is LOST and all we see is an empty file w/ the date stamp

-rw-r--r-- 1 abcadmin abcadmin 0 Sep 25 23:59 Process100Server.log-2023-09-24.log

In fact, a few days of this and we see rolled (date-stamped) files that are ZERO bytes:

-rw-r--r-- 1 abcadmin abcadmin 2346943 Sep 27 15:56 Process100Server.log
-rw-r--r-- 1 abcadmin abcadmin 0 Sep 24 23:59 Process100Server.log-2023-09-24.log
-rw-r--r-- 1 abcadmin abcadmin 0 Sep 25 23:59 Process100Server.log-2023-09-25.log
-rw-r--r-- 1 abcadmin abcadmin 0 Sep 26 23:59 Process100Server.log-2023-09-26.log

In summary, only the NON-date-stamped files show any content...Once the file is date stamped, its content is gone. At a loss with this. Any insight is appreciated.

Tried changing the Appender type and file name pattern... no effect.
